With their first game of the season, Vincent Kompany's side have delivered a message to the rest of the Bundesliga - Bayern are as strong as ever.
They were superior in every aspect from front to back, across the whole game, and left Leipzig ragged in a vain attempt to stop their attacking stampede.
On the wings, Bayern shone. Olise and full-back Konrad Laimer doubled up on the right, overlapping to beat the visitors' defence and carve out openings.
Their efforts constantly stretched Leipzig, got Olise into the right spaces to get two goals of his own and allowed the rest of their attacking line to work their magic in the middle.
Kane sat deeper than a traditional striker, but was the same threat as ever, timing his runs to perfection to latch on to Bayern's intricate passing moves and deliver the clinical touch when needed.
Leipzig were sloppy, misplaced their passes and were not switched on to the home side's runs. Gnabry and Joshua Kimmich enjoyed their superiority going forwards, repeatedly gifted the space to display their talents on the ball.
Leipzig's back four was simply not good enough to cope, but even if they had extra numbers in defence they never looked like they would have been able to stop Bayern's ruthless attacking machine.
This is a new-look Leipzig side, guided by a new boss in Ole Werner, and it's clear they are very much a work in progress.
